Value missing from Slicer

[Anonymous]

Data value missing in Slicer.

Below "Type" "Category" "Detail" pulled from same table "Master Category", except "Date" was pulled from Calendar table

When i select like below, Value "C" and "F" and "G" had gone missing from Slicer "Detail",  you can see from the table on the left, those 3 values exist.    Any1 know why? 

The relationship is as below, 3 tables were connected to a "Master Category" table which those slicers pulled from.  And all the dates from those 3 tables were connected to the "Calendar date"

Which tables are "c" "f" & "g" from? I think @ImkeF is right; it's a relationship issue between the tables.

Try setting the relationship between Mater Category and Data -AD from bidirectional to single.

@ImkeFoh yes, it works, why this one is "both" rest all "single", wired.  thanks!!
